We measured the spin rectify effect and the inverse spin Hall effect in Nb-doped SrTiO3 by injecting the spins from ferromagnetic thin films to SrTiO3 using spin pumping. It was shown that the spin injection is increased when the doping level is increased. However, the spin Hall angle decreases when Nb occupies more than ∼2% of the Ti sites, which is due to that beyond this concentration, the electron contributed the spin Hall effect is from the d-orbitals of Nb instead those from the Ti. Our work points to the importance of orbital occupations in the (inverse) spin Hall effect. We may explore controllable spin and charge interconversion in oxide spintronics.
